invention relates to a machine for 'oi-ieparing nail knobs and particularly to t inachine wherein a pair oi opposed porcelain. knobs are mounted on a nail with t or Without holding or protecting washers. lit has been customary in the past to secure the knobs perrnanentiy on the nail by crimping otherwise enlarging the steniot the nail. I provide an attachment for nail knob machines whereby the crimping may, if desired, be eliminated," the knobs being held in position on the nail by. a metal washer Which is driven upon the nail and is clamped closely thereupon. My purpose 1s to provide means "for feeding such a Washer to a nail engaging punch and tor providing the necessary punch and the means tor using it. Another object is to provide unit means for the washers and for operating the punch @ther objects vviil appear from time to time in the course oi the specification.

ii illustrate my invention more or less diagrammatically in the ioilovving drawings, wherein:

Figure 15 is a plan view of the parts shown in Figure 13 with the hopper blade in thelovver position.

Like parts are indicated bylike symbols throughout the drawings.

A is a machine bed referably formed of a single casting which may be supported on any suitable framework not herein shown in detail. It is channeled at A adjacent the front of the machine, and Within-the channel A is any suitable conveyor belt A upon which the pairs of axially perforated nail knobs may be placed for conveyance invyardl from the ed e of the machine. The pairs 0 porcelain blanks are carried forward into the notches .A" of the circular rotating carrier table A! Which is given an in termittent rotation by any suitable means not herein shown in orderto carry the nail lrnob pairs forward by a step by step rotaion.

At the position marked X each pair nail knobs halts during this step by step motion and the nail is passed therethrougli. if desired, Washer may be fed above the lcnobs and beneath thcnail which then trans-- tines the Washer before penetrating the knobs. d vhen the nail knob pair reaches the position marked Y in Figure l, a second washer is fed beneath the assembly and the na l is driven down through it. At the positionniurlred Z the stem of the nail heath the nail knobs and washers may be suitably enlarged, erinuned, or deformed to prevent reinoval oi lrnobs and washers iron the nail.

a nut rotating on the shaft B Mounted to rotate with the gear B is the cam element C which is rovided with a spiral cam surface C and an inwardly inclined surface C terminating in a plurality of scallopsCt Pivoted to C as at D is the link D pivoted as ht D to hopper blade D which is adapt ed to be oscillated in a vertical slot opening; into the bottom of the hopper D. This hopper comprises in part opposed inclined converging sections, D, D and is provided with. an outward extension D to the outer reins horn end of which is pivoted the hopper blade lever D The hopper is mounts ed on the upper ends of a plurality of ver tical rods, D, the lower ends oi which are secured inuny suitable fashion to the upper euriace of the machine as at The top the machine is apei cured as at D to perinit the passage of the link D The hopper blade is provided with upper slot D which is adapted to pick up the thin perforated metal washers with which the hopper is kept filled. As it rises, these washers ride forward in the slot and are dropped into the upper end of the washer chute E and dropped down it to the inclined portion E D are agitating and collecting wires which tend to drop washers into the slot. The lower'portion of the chute E is formed of two opposed. spaced plates W, E secured by the screws E; The blade is slotted to receive the tongue D which serves to hold the cove l) in the top edge the blade D in accurate alignment with the en trance to the chute K is a kick-out lever adapted to penetrate the top portion of the chute E. It is keyed upon any suitable rctatahie sleeve or shaft K mounted upon the oi the hop r D.

The lower end of this rod is adapted to be contracted by an adjustable set screw K mounted upon the hopper blade lever I). It will be run derstood that as the hopper blade is raised and lowered through the hopper the kickout is alternately liftec the top of the chute and allowed to kick back into it in response to the action of the spring K drawing down upon the rod K Pivoted as at F beneath the chute section E is the U-shaped yoke F slidably mounted chute shown in Figure 6, and are adapted to penet "ate the chute at a distance apart substanially equal to the diameter of one Washen Une arm of the yoke is upwardly continned, has integral with it a perforated screw threaded boss F penetrated by a stop screw F provided with a lock nut F. the spring F is compressed between the boss F and the plate E and tends to thrust the boss outwardly away from the chute. The set screw F mounted in. the machine frame serves to limit the outward travel of the yoke. The yoke F is provided adjacent its pivot with an outward projection or bracket Gr perforated as at G and provided with a pin G passing through the perforation and adapted to penetrate the u per end G of the pin G, the lower end 0 which slidably engages or passes through a bracket G on the lever mm H later to be described. The

Positioned on the top of the punch IS the washer, the perforation of which overfit! punch is normally operating and t lies the perforation of the punch. The pgging of the cam surface serves to oscil ate the punch and place the washer into horizontal position, it being of course, fed to the punch on edge. Therefore, as the punch rises about the nail, it carries the washer with it, the washer aperture forming a tight fit, but not suificiently tight to overcome the pressure of the spring K. The nail is kept ieldingly in position by the nail engaging cad J which engages the head of the nail. ihe spring K is compressed and as the check nut makes a normal movement with only about one-eighth inch it indicates t at the at the washers are properly co-operating therewith.

If for any reason, the washer feed jams and no washers are fed forward the punch will pass about the nail and without lifting it, and the nuts 3 will not move above the cap J If for any reason a washer without an aperture or with too tight an aperture is fed to the punch, the nail will of course be unable to penetrate the punch, and will be forced upwards through K and lifting the nuts K and secondly compressing the head J against the plug J, compressing the spring K to the full stroke of the punch.

Thus the machine automatically indicates the failure of the washer feed, by a want of any movement of the nuts J and the feed of a defective washer, by the abnormal movement of the nuts J and the stem on which they are mounted. Furthermore, the springs K K automatically prevent any damage from such defective feed.

It will be understood that in the present specification and claims the term pair or pairs of nail knobs is used to denote an as sembly comprising a pair of nail knob ele: ments mounted on or to be mounted on a single nail. The completed knob commercially so called comprises a pair of nail knob elements mounted on a. single nail and preferably held permanently in position on said nail.
